A team of researchers at the University of Kansas recently excavated a fossilized upper jaw with teeth completely intact in the Hell Creek Formation in Montana. While tests still need to be done to confirm its nature, it's small and bears a terrifying resemblance to larger Tyrannosaurus rex fossils, suggesting the ancient teeth came from a child born about 66.5 million years ago.

New dinosaur with razor-sharp claws and jagged teeth unearthed in Argentina

Parts of the fossilized skeleton of a large, meat-eating dinosaur with razor-like claws and sharp, jagged teeth, which once roamed the plains of South America and Australia millions of years ago, have been unearthed in Argentina, according to researchers.

Mystery dinosaur skeleton sells at Eiffel Tower auction for more than $2 million

The 150 million-year-old, largely-intact skeleton of a still-unknown species of dinosaur went to auction today in Paris and sold for more than two million dollars - and if paleontologists’ hunches prove true, the mystery winning bidder may get a chance to bestow a name on a previously undiscovered species.

The remains of the prehistoric predator – which is 30 feet long and 9 feet high - were discovered at Morrison Formation site in Wyoming in 2013.

I hate to ruin the flow of your thread, but I have a few questions since you seem to be an expert.

Mammals like elephants and rhinos have to have giant dicks to be able to fuck. How did dinosaurs with no dicks with similar body dimensions albeit in some cases to the extreme perform this task?

Also, in a documentary, they showed a brontosaurus laying eggs into a ditch. Many eggs that have to drop a large distance. They showed the eggs dropping through a long membrane like tube of tissue to go into the hole. I guess this is to explain how the eggs didn't break. How do they know about this tube from some fossils?

Dinosaurs are often depicted as fierce creatures, baring their teeth, with tongues wildly stretching from their mouths like giant, deranged lizards. But new research reveals a major problem with this classic image: Dinosaurs couldn't stick out their tongues like lizards. Instead, their tongues were probably rooted to the bottoms of their mouths in a manner akin to alligators.

BUENOS AIRES: Giant dinosaurs lived on Earth much earlier than previously thought, according to a team of excavators in Argentina who discovered the remains of a 200-million-year old species.

The species, baptized Ingenia prima, was about three times the size of the largest Triassic dinosaurs from its era. It was discovered in the Balde de Leyes dig site in San Juan province, 1,100 kilometers (680 miles) west of the Argentine capital Buenos Aires.

Newly discovered armored dinosaur from Utah reveals intriguing family history

Fossils of a new genus and species of an ankylosaurid dinosaur—Akainacephalus johnsoni— have been unearthed in the Kaiparowits Formation of Grand Staircase-Escalante National Monument (GSENM), in Kane County, southern Utah, U.S.A., and are revealing new details about the diversity and evolution of this group of armored dinosaurs. Expected to look like other North American Late Cretaceous ankylosaurid dinosaurs with smooth bony armor on the skull, the new research suggests just the opposite and indicates that the defining features of Akainacephalus, specifically the spiky bony armor covering the skull and snout, align more closely with Asian ankylosaurids, who also have more pronounced spikes covering their skulls.

Paleontologists have discovered what they say is a completely unexpected desert-dwelling pterosaur that lived in what is now Utah, the United States, about 210 million years ago. The discovery of this early pterosaur, reported in the journal Nature Ecology and Evolution, sheds new light on early pterosaur anatomy and development.

T-rex redesign: The Jurassic meat-eater as you’ve never seen him before (PHOTOS)

Makers of an open world dinosaur video game say they have created the “most accurate” depiction of the meat eating monster T-rex yet, thanks to painstaking study of research by paleontologists and other dino experts.

The Saurian game, which allows users to play the lifespan of six dinosaurs including tyrannosaurus and triceratops, prides itself on the scientific accuracy of its world. The game is a simulation of the Hells Creek Formation ecosystem, an area around the US state of Montana where fossils belonging to scores of dinosaurs were pulled from the soil.
